Heating in buildings is at the core of energy consumption. Thus decarbonise energy sources is crucial to reduce associated emissions. Geothermal district heating is defined as the use of geothermal sources to supply heat to a group of buildings through a distribution network. The main benefits of geothermal sources are provision of local, and flexible renewable energy. Even though there are plenty of geothermal sedimentary reservoirs to use, there is sometimes heterogeneities of geological properties that limited productivity. The goal is then to optimise the draining area and thus to increase the overall energy extracted from the ground. This multidrains technology steps up the efficiency of a geothermal solution.
The Environmental Benefits
- •Around 80% more efficient compared to a conventional solution
- •Saving 640,000 tons of CO2 over 30 years exploitation period compared to a fossil energy solution
The Financial Benefits
- •Considering +20% of drilling costs, the productivity is increased drastically
- •Only 2 innovative wells drilled instead of 4 conventional wells needed to reach the flowrates expected to cover network needs, means around €8 million saved for a project
- •Use geothermal source means stable heat price over time
